Introduction
Abaqus is used for solving problems in Computational Fluid Dynamics (CFD) and related multiphysics. It supports GPU as well as CPU execution.
GPU Support
Many Abaqus jobs that use a GPU will execute up to four times faster than a job that only uses CPU processors.
Note also that running Abaqus with a GPU still requires CPUs for many operations, particularly with post-processing analysis. It is recommended that you request at least 4 CPUs for each GPU requested.

Sample Batch Script for Abaqus Using a GPU
The following Slurm batch script shows a typical job that uses a GPU.
#!/bin/bash
#SBATCH -J Scan_ShearWave_1
#SBATCH -D /work/researchit-staff/jedicker/abaqus/testjob
#SBATCH -N 1
#SBATCH -n 32
#SBATCH --partition=nova
#SBATCH --ntasks-per-node=32
# It is a good idea to tell SLURM to use a large amount of memory. 128000 = 128GB.
# 4GB of memory per processor is recommended.
#SBATCH --mem=128000
#SBATCH --time=24:00:00
#SBATCH --error=Scan_ShearWave_1.%j.error
#SBATCH --output=Scan_ShearWave_1.%j.output
#SBATCH --mail-type=BEGIN,FAIL,END
#SBATCH --mail-user=jedicker@iastate.edu
cd /work/researchit-staff/jedicker/abaqus/testjob
# Load the Intel compiler and Abaqus software.
module load abaqus/2025
# Abaqus doesn't support SLURM natively. So, the script below gets the list of
# allocated hosts from SLURM and uses it to construct the mp_host_list[] variable.
# It copies the global custom_v6.env file from the global Abaqus "site" directory and
# adds the mp_host_list[] line to the bottom of the abaqus_v6.env file in the current folder.
# The number supplied to create_abaqus_mp_host_list.sh is the desired number of procs per node.
create_abaqus_mp_host_list.sh 32
